  • Device having a structured coating for adhering to other surfaces
    Patent number: 11583381
    Abstract: A device having a structured coating for adhering to rough, in particular biological, surfaces, includes a carrier layer, wherein a plurality of protrusions is arranged on the carrier layer, which protrusions each comprise at least a shaft having an end face pointing away from the surface, and wherein a further layer is arranged at least on the end face, wherein the layer has a different modulus of elasticity than the protrusion in question. The further layer can also fill the intermediate spaces between the protrusions such that an internal structured coating is produced.
    Type: Grant
    Filed: July 14, 2021
    Date of Patent: February 21, 2023
    Assignee: Leibniz-Institut für Neue Materialien gemeinnützige GmbH
    Inventors: Eduard Arzt, Sarah Fischer, Klaus Kruttwig, René Hensel, Bernhard Schick, Gentiana Wenzel
